Title: Continuous process for alkylating an aromatic hydrocarbon
IPC: C07C15/107
Filed: 1964-07-01
Abstract: Detergent alkylate is obtained by contacting an excess of aromatic hydrocarbon with a C9-C18 alkyl chloride in a first zone in the presence of a red oil complex catalyst to effect condensation of a major proportion of the alkyl chloride, separating red oil from the effluent and contacting the remainder in a second zone with aluminium to complete condensation, separating red oil from the effluent for use as catalyst in the first zone and recovering alkylate from the remainder.  In a preferred embodiment partially chlorinated n-paraffin containing 10-50% mol. of alkyl chloride together wit fresh feed n-paraffin boiling in the range 300-605 DEG  F. and 2-25 mols. of aromatic hydrocarbon per mol. of chloride are contacted with red oil complex forming 5-25% by volume of the reaction mixture are contacted in the first zone at 100-185 DEG  F. for 3-15 minutes to condense 90-95% of the alkyl chloride.  Part of the red oil complex is recycled and an amount equivalent to that from the second zone is discarded.  Hydrogen chloride may also be separated and washed with the n-paraffin feed to recover organic compounds. Consumption of aluminium in the second zone is regulated either by using a zone packed with metal and limiting the amount of hydrogen chloride introduced, e.g. 1-30 parts per 1000 parts of feed or a saturated solution, or by feeding aluminium at a controlled rate of 0.03-0.1 gram atom per gram atom of chlorine in the chlorinated paraffin feed to the first zone. Red oil may be maintained in an amount of 5-25% vol. of the reaction mixture.  Reaction is effected at 100-185 DEG F. for 0.3-15 minutes. Red oil is separated and passed to the first reactor and/or recycled to the second.  The product is separated into aromatic hydrocarbon for recycle, n-paraffin which is partially chlorinated and passed to the first zone and alkylate boiling in the range 520-730 DEG  F.

Title: Automatic control systems for aircraft
Inventor: MEREDITH FREDERICK WILLIAM
IPC: G05D1/08
Filed: 1947-10-10
Abstract: 669,472. Automatic control systems for aircraft. SMITH & SONS (ENGLAND), Ltd., S. Oct. 5, 1948 [Oct. 10, 1947], No. 27310/47. Class 38 (iv). In an aircraft automatic control system, the rudder and elevators are simultaneously controlled in accordance with the angle of bank and the deviation of the rate of turn about the gravity yaw axis so as to maintain the latter at a predetermined value. The invention is applied to a system of the type disclosed in Specification 617,240 and three embodiments are described which employ cross-feeds between the rudder and elevator control systems; two of the methods incorporate a transfer of electrical energy between the rudder and elevator controls, and a third incorporates torque motors at the rate of pitch and turn gyro which are energized by cross-feed means. As shown, Fig. 1, an aircraft is stabilized about three mutually perpendicular axes by the three rate of turn gyros 1, 5, 8, which are mounted on the gimballed platform 11, Fig. 2, and which respectively control the rudder, elevator and ailerons through their associated amplifiers and motors. The rotors of the inductive resolvers 51, 52 are geared to the shaft 14 of platform 11 and the stators supply two outputs each which form the direct and cross-feed supplies to the elevator and rudder servor. A banked turn is executed by rotating 11 about the axis 14 whereon both the rudder and elevator controls are energized from the tangent potentiometer 24, mounted on shaft 14, while further signals are applied to both controls from the rate of turn and pitch gyros 1, 8 so that the craft is banked and turned in a horizontal plane without side slip at normal crusing speed. In a second modification, not shown, the inductive resolvers are replaced by potentiometers operated by shaft 14, each of which is fed from one control system and feeds into the other. In the third modification, Fig. 11, which is A.C. operated, the movement of gyro 1 is opposed by torque motors 64, 65, 66, 67, which are respectively energized from the signal generator 22 of the rudder 2, rate of turn signal generator associated with 1 through the differential circuit 63, the control circuit of elevator 6, and the tangent potentiometer 24. Similarly the three torque motors 64, 65, 66 which oppose the rate of pitch gyro 8 are energized respectively from the elevator signal generator 22, rate of pitch signal generator and from the rudder control circuit. A D.C. operated version (not shown) is also described. Specifications 576,248, 576,249 and 669,476 also are referred to.

Title: Improvements in or relating to cooling systems
IPC: F01P7/04
Filed: 1956-09-07
Abstract: 824,783. Screw fans. FORD MOTOR CO. Ltd. Sept. 7, 1956 [Sept. 12, 1955], No 27421/56. Class 110 (1). [Also in Groups XXVII and XXIX] A water pump rotor 70, Fig. 2, forms the impeller 33 of an hydraulic coupling, the turbine 32 of which is fast with an enginecooling fan 23, liquid being supplied to and released from the coupling under thermostatic control to engage and disengage it and the coupling having means to fill it with gas as it is emptied of liquid and vice versa. An enginecooling system incorporates a radiator 22, Fig. 1, the fan 23 and the water pump housing 21 with deliveries 73, 74 to the engine block and intakes 71, 72 from the radiator outlet 81, and via a venturi 25 and a thermostat 26, from upstream of a thermostat 27 in the return 75 from the engine block to the radiator. Connections 84, 86 lead from the venturi throat and radiator air space to bores 65, 60 leading into the coupling housing 35 via ducts 66 to 68 and 61 to 63 respectively. When the engine is hot, the thermostats 26, 27 are respectively shut and open as shown so that water fills the coupling housing 35 and also circulates through the radiator 22. Below a predetermined temperature, the thermostats 26, 27 open and close, in staggered relationship if desired, and the flow through the radiator 22 is stopped, whilst the depression due to flow through the venturi 25 evacuates liquid from the coupling housing 35 and draws air and/or vapour thereinto via the connection 86. A water seal remains at the periphery of housing 35 which to this end may be annularly corrugated near its outer circumference. The position of duct 66, Fig. 1, not lower than the pump centre-line helps to retain water in the central area for lubrication. The members 32, 33 may be of moulded plastics or powdered metal. Water seals 50 and vents 45, 49 are provided. The engine crankshaft drives the rotor 70 via a belt 40. Modifications.-In Fig. 4 the coupling housing has only one entry bore 60, which may be placed by a thermostatic two-way valve in communication with the radiator air space or engine block, the coupling being self-evacuating by two venturi aspirators 90 and having an 0.03 inch diameter impeller drilling 97 to assist filling with liquid. The intake 71 (Fig. 3, not shown) connects with the radiator outlet as before and the intake 72 directly with the return 75 upstream of its thermostat as before, the deliveries 73, 74 being unaltered. In Fig. 6 (not shown) the two-way valve is replaced by a thermostatically controlled connection to the engine block only, the coupling on liquid evacuation filling with gas by vaporization and air expansion only. In all embodiments, high engine and corresponding water pump speeds giving high system pressures may cause fan stoppage by actuating a pressure-sensitive valve; in Fig. 1, such a valve opening at high pressures may be located between the venturi 25 and thermostat 26, or in the thermostat, and in Fig. 6 such a valve closing at high pressures may be located in the thermostatically controlled engine block connection.

Abstract: 850,013. Parametrically excited resonators. KOKUSAI DENSHIN DENWA. KABUSHIKI KAISHA. Sept. 7, 1956 [Sept. 16. 1955], No. 27500/56. Class 40 (9). Parametrons are coupled by transformers. The transformer circuit can be adjusted to transmit a signal with the phase unchanged, with the phase reversed (a NOT signal) or with an intermediate phase. The parametron shown in Fig. 1A is described in Specification 778,883. The two cores F1, F2 are excited from terminals E, by a direct current bias and an alternating current of twice the characteristic frequency of the tuned secondary circuit which includes condenser C. The phase of the output voltage on terminals 0 is one of two phases differing by 180 degrees. The phase of the oscillation is determined by a pilot signal on terminals In when excitation commences. In Fig. 4 a parametron P1 is coupled to parametrons P2, P3, P4 by transformers T2, T3, T4. The coupling factor may be adjusted by an impedance Z. In an embodiment, Fig. 5, three parametrons P1, P2, P6 and three transformers T1, T2, T6 are moulded in a slab of plastic resin and four slabs are assembled in a casing. As in Fig. 4 the terminals A, B of P1 are connected to the primaries of transformers T2, T3, T4 which in this embodiment comprise a single loop of wire. The output of a parametron P1, Fig. 6, may be fed to a coil La linking the cores of a second parametron P2. The signal is transmitted to the tuned circuit C, l1, l2 of P2 by transformer action in the parametron itself. The phase of the signal transmitted between parametrons P1, P2, Fig. 7, may be controlled by adjusting a resistor R and a capacitor Co in the primary circuit of transformer T. Reference has been directed by the Comptroller to Specification 778,883.
